# 2.获取图片地址 #

String urlencodeKewy = URLEncoder.encode(wordKey, "GBK");
                //百度图片url，返回图片的json数组
                String baiduImageUrl = "https://image.baidu.com/search/acjson?tn=resultjson_com&logid=10660754132115598609&ipn=rj&ct=201326592&is=&fp=result&" +
                        "queryWord="+wordKey+"&cl=2&lm=-1&ie=utf-8&oe=utf-8&adpicid=&st=&z=&ic=&hd=&latest=&copyright=&" +

                HttpURLConnection connect = (HttpURLConnection) url.openConnection();
    
                //获取url对应的inputStream
                is = connect.getInputStream();
    
                //转换后的String
                String baiduImageStr = IOUtils.getIOUtilsInstance()

                    System.out.println(imageJosn.getString("hoverURL"));
                }

# 3.下载图片 #

public static void download(String saveFileName,String url,String keyWord) throws Exception{
            File file=new File(saveFileName);
            if(!file.exists()){
                file.mkdir();

            URL url1 = new URL(url);
            URLConnection uc = url1.openConnection();
            InputStream inputStream = null;
            FileOutputStream out = null;
            try {
                inputStream = uc.getInputStream();
                out = new FileOutputStream(saveFileName);
                int j = 0;
                while ((j = inputStream.read()) != -1) {
                    out.write(j);
                }
            }catch (Exception e){
                e.printStackTrace();
            }finally {
                if(out!=null){
                    out.close();
                }
                if(inputStream!=null) {
                    inputStream.close();
                }
            }
    
        }

# 4.重复下载图片 #

public static void main(String[] args){
            String wordKey = "餐具";
            for(int i=0;i<30;i++){
                int startNum=i*30+1;
                downloadpic(wordKey,startNum+"");
            }
        }
